XmlmmCIF equivalent: struct_ncs_oper Data items in the STRUCT_NCS_OPER category describe the non-crystallographic symmetry operations. Each operator is specified as a matrix and a subsequent translation vector. Operators need not represent proper rotations. XmlmmCIF equivalent: struct_ncs_oper/code A code to indicate whether this operator describes a relationship between coordinates all of which are given in the data block (in which case the value of code is "given"), or whether the operator is used to generate new coordinates from those that are given in the data block (in which case the value of code is "generate"). XmlmmCIF equivalent: struct_ncs_oper/details A description of special aspects of the non-crystallographic symmetry operator. XmlmmCIF equivalent: struct_ncs_oper/matrix11 The [1][1] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix12 The [1][2] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix13 The [1][3] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix21 The [2][1] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix22 The [2][2] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix23 The [2][3] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix31 The [3][1] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix32 The [3][2] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/matrix33 The [3][3] element of the 3x3 matrix component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/vector1 The [1] element of the 3 element vector component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/vector2 The [2] element of the 3 element vector component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/vector3 The [3] element of the 3 element vector component of a non- crystallographic symmetry operation. XmlmmCIF equivalent: struct_ncs_oper/id The value of _struct_ncs_oper.id must uniquely identify a record in the STRUCT_NCS_OPER list. Note that this item need not be a number; it can be any unique identifier.
